Claim 5

A self-locking mechanism as in claim 1, wherein the retainer includes a cover extending from the second member to the initial position overlying the larger opening portion of the keyhole slot, spring means biasing the cover and retainer to the initial position, the retainer being so constructed and arranged as to be movable against the spring means to uncover the larger opening portion of the slot to permit passage of at least the head of the pin through the slot, the head of the pin being of a greater size than the smaller opening portion of the slot, the smaller diameter portion constituting a neck portion of a diameter less than that of the smaller opening slot portion permitting sidewise movement of the pin neck portion into the smaller opening slot portion to lock the pin and second member together.

Claim 6

A self-locking mechanism as in claim 3, the cover comprising a plate-like element secured to the second member, withdrawal of the retainer cover from the position overlying the slot permitting downward movement of the cover below the head portion of the pin whereupon subsequent release of the cover and the bias of the spring means engages the cover with the smaller diameter portion of the pin urging the same into the smaller diameter opening portion of the slot.

Claim 7

A self-locking mechanism for interconnecting a vehicle accelerator pedal connected cable to a carburetor throttle body lever, including a first lever connected to the carburetor throttle body and having a nailhead type pin at one end projecting outwardly therefrom, the pin including first head portions of a large diameter connected to a neck-like portion of lesser diameter, a second member cable connected to the vehicle accelerator pedal for movement thereby, the second member having a keyhole slot shaped aperture at one end for a mating cooperation with the pin upon insertion of the pin through the aperture, the aperture including a first portion of a diameter larger than the pin large diameter head portion, and a second aperture portion having a diameter between the lesser and large pin portion diameters, and a spring biased movable retainer normally overlying a portion of the slot preventing movement of the large diameter pin portion through the slot, the retainer being movable away from the aperture against its spring bias to permit insertion of the large and lesser diameter pin portions through the slot, release of the retainer moving the, retainer against the pin head lesser diameter portion and biasing the lesser pin portion into the second aperture portion with the retainer beneath the large head portion of the pin to lock the pin against withdrawal through the slot.

Claim 8

A self-locking mechanism for interconnecting a vehicle accelerator pedal connected cable to a carburetor throttle body lever, including a first lever connected to the carburetor throttle body and having a nailhead type pin at one end projecting outwardly therefrom, the pin including first head portions of a large diameter connected to a neck-like portion of lesser diameter, a second member cable connected to the vehicle accelerator pedal for movement thereby, the second member having a keyhole slot shaped aperture at one end for a mating cooperation with the pin upon insertion of the pin through the aperture, the aperture including a first portion of a diameter larger than the pin large diameter head portion, and a second aperture portion having a diameter between the lesser and large pin portion diameters, and a spring biased movable retainer normally overlying a portion of the slot preventing movement of the large diameter pin portion through the slot, the retainer being movable away from the aperture against its spring bias to permit insertion of the large and lesser diameter pin portions through the slot, release of the retainer moving the, retainer against the pin head lesser diameter portion and biasing the lesser pin portion into the second aperture portion with the retainer beneath the large head portion of the pin to lock the pin against withdrawal through the slot.

Claim 9

A self-locking mechanism for interconnecting a vehicle accelerator pedal connected cable to a carburetor throttle body member, including a first lever connected to the carburetor throttle body and a second member cable connected to the vehicle accelerator pedal for movement thereby, the first lever having a nailhead-like pin projecting from one end comprising a large diameter land connected to a reduced diameter neck-like portion, the second member having a keyhole shaped slot at an end to be engaged by the pin of the first lever, the slot having a stepped diameter opening with a smaller diameter portion of a size to accept only the neck-like portion of the pin therethrough, and a diameter slot opening being of a size to receive the large land and the neck-like portion therethrough, linear movement of the member and lever in a direction to separate the member and lever engaging the neck-like portion in the smaller diameter slot opening after insertion of the large land and neck-like portion through the slot opening, and retainer means to bias the neck-like portion of the pin into the smaller slot opening and lock the pin against withdrawal through the slot, said retainer means including a member slidably attached to the first lever and spring biased into a position overlying a portion of the slot preventing passage of the pin therethrough, the member being movable against the bias to a position uncovering the latter slot portion to permit passage of portions of the pin therethrough, return movement of the retainer member through the slot engaging the retainer with the neck-like portion and moving the reduced neck-like portion of the pin smaller diameter slot opening and a portion of the retainer beneath the larger land to lock the pin against withdrawal through the slot.

Claim 10

A self-locking mechanism for interconnecting a vehicle accelerator pedal connected cable to a carburetor throttle body member, including a first lever connected to the carburetor throttle body and a second member cable connected to the vehicle accelerator pedal for movement thereby, the first lever having a nailhead-like pin projecting from one end comprising a large diameter land connected to a reduced diameter neck-like portion, the second member having a keyhole shaped slot at an end to be engaged by the pin of the first lever, the slot having a stepped diameter opening with a smaller diameter portion of a size to accept only the neck-like portion of the pin therethrough, and a diameter slot opening being of a size to receive the large land and the neck-like portion therethrough, linear movement of the member and lever in a direction to separate the member and lever engaging the neck-like portion in the smaller diameter slot opening after insertion of the large land and neck-like portion through the slot opening, and retainer means to bias the neck-like portion of the pin into the smaller slot opening and lock the pin against withdrawal through the slot, said retainer means including a member slidably attached to the first lever and spring biased into a position overlying a portion of the slot preventing passage of the pin therethrough, the member being movable against the bias to a position uncovering the latter slot portion to permit passage of portions of the pin therethrough, return movement of the retainer member through the slot engaging the retainer with the neck-like portion and moving the reduced neck-like portion of the pin smaller diameter slot opening and a portion of the retainer beneath the larger land to lock the pin against withdrawal through the slot.
